Can someone post up the rules for nitrous according to nhra. I know a couple people were questioning if the line had to be inside the car/outside of the car etc.

 

The feed line can be on the inside.

You must have a blow down tube if the bottle is not seperated from the passenger compartment by a sealed bulkhead.

Some tracks are requiring a SFI jacket if running nitrous.

 

It depends on where you are in the states...
Here in Texas, one of our tracks... Ennis checked my line to make sure it went outside the car.. At first the tech was checking to see if it was secured correctly, then he seen it was running outside and moved on..

The blow down for a camaro is a major deal at the tracks... NHRA required..
For camaros alot of guys do bulk heads...
picture attached....
Bulk heads are NHRA approved.. its in the book...
